Seven hours of data, combined exposure lengths, with Optolong l-eXtreme filter for hydrogen alpha.
I experimented with a new set up last night and captured three targets. The third is M31: the Andromeda Galaxy. The camera I used is a Sony Alpha 6300 mirrorless (unmodified) along with a Samyang 135mm manual focus f/2 lens. No telescope!
Captured from our villa in Grand Cayman using the portable Sky Watcher Star Adventurer GTi mount.
A first look at the Andromeda Galaxy as it reappears in the fall of 2022. Captured unguided on the Sky Watcher Star Adventurer Mini (SAM).
5 nights of dedicated imaging for 15 hours of RGB (combination of 45-second, 1-minute and 3-minute exposures) and 5 hours of narrowband (Optolong l-eXtreme). Honestly, I processed this about four or five times before getting to a result I was satisfied with... future revisions may come!
The Andromeda Galaxy for 24 minutes in one-shot color.
An interim stack of multiple sessions for a 2022 project to achieve as detailed an M31 as possible.
A detailed capture taken by composing multiple exposures and filters.
A dramatic version of M31 with a bit more saturation combined from 6 1/2 hours of exposure taken over the course of 2022.
First attempt at capturing this galaxy with nothing but an ordinary camera and zoom lens.
Just off the edge of the Andromeda Galaxy is one of two satellites orbiting the Milky Way's neighbor: M32, a dense cloud of stars that are classified as a dwarf, early-stage compact elliptical galaxy.
Over 2,000 10-second exposures went into stacking 6 panels that were blended to produce this capture of Andromeda with neighboring galaxies M32 and M110.
A detailed image taken over just a few minutes with a remotely controlled telescope in Spain.
